I'd go with Hyperspin, personally. There are a lot of providers and most of them aren't very good. It gets as bad as one showing 66% (false) downtime. You want something fairly redundant and not just monitoring from a single location.

Host-Tracker.com is also good, with monitoring from 60 + locations, around the world.
If you want monitoring + reboot, I would suggest PSM (www.platinumservermanagement.com) , it costs just $10 a month, & they reboot your server if it goes down.
If you want full management, including monitoring, again go with PSM, it is just $29/month (& $19/month for more servers) , I use them myself.
Why don't you utilize the web site monitoring services from the company you host your web site with. Say ServerPoint.com and HostWW.net provide this features along with their web hosting services. I think it's very convenient for their clients not to waste extra money.
I think that all of you do understand that in 95% cases all that monitoring figures are for web hosting company web site. Which for sure can have uptime for last several years.

I used Hyperspins 1 minute monitor for a few years and it was the most accurate compared to some other well known monitors which gave me false reports all the time.
